It took 5 years of working in a hospital setting and several coarse from IJCSA To truly understand how effective the methods used in Medical cleaning can be, and how essential it can be moving forward.  

In the medical field, or shall I say the environment service department, we disinfect accordingly and to the patient.  Every situation nor person is the same, some might be sick, while others might require surgery or even minor procedures all have a specific way of being cleaned using a specific chemicals for the material or surface to be cleaned.  More importantly these solutions are highly effective when used properly, and knowledge is key!  

When you train, and educate yourself and others on the importance of maintaining a safe, clean, environment for your guest, customer, staff, and residents, and more importantly how to properly clean, kill time depending on surfaces and solutions being used can really help your building cleanse excel, helping keep everyone safe.  (HAI) can effect residents just as much as a resident, so using universal precautions before entering a place can also play a factor.  

Consistency also plays a major factor, I truly believe in order to meet medical standards, the residential and commercial buildings have to be more consistent when cleaning, making it more of a factor, also a major difference is the concentrated wipes used to disinfect surfaces should be primary.  I would especially use these wipes in common areas desks, hand rails, air vent panels, all bathrooms, mail room and any other place of direct or indirect contact. 

In conclusion, both places respectfully have great standards of cleaning there respectable environment, but in these times we should be empathizing excellence.  If most places find the medical and residential or commercial workplaces similar!  Why not be held to the same standard!  We are in the business of killing bacteria, not to slow them down.  I would also hold the residents or employees responsible for there stations as well.  Everyone must do there part in a collective effort to control exposure, so my last request is all staff not only porters, housekeeping, and janitors, should be responsible, especially if it is your own workspace.  Minimizing the Porters job by a small fraction, allowing them to concentrate more on common areas.
